How Much Does a Fractional CFO Cost Per Month?

For a $1-5M service business, a fractional CFO commonly runs $3,000 to $8,000 a month. That number tracks two things: how many days they work, and how heavy your decisions have gotten. Light advisory sits at the bottom. Raises, sales, and turnarounds push you to the top. Practitioner observation, not a published rate card.

What drives the monthly price?

You are not buying hours. What you pay for is judgment, and how often you reach for it. Several specific things move the fee, and the more of them your business carries, the higher it lands.

• Days per month. A few hours of review is one price. A few full days running your forecast is another.
• Decision weight. Raising money, juggling multiple service lines, or eyeing a sale all need more horsepower than a steady business running the same playbook.
• The state of your books. If your numbers are not reliable yet, that is a controller problem first, and someone has to fix it before the CFO work even starts. The three finance layers stack in a fixed order, and skipping one costs you.
• Scope. On-call advice is cheap. Owning the model, prepping lender decks, and sitting in on financing conversations is not.

A rough monthly map for a $1-5M service business

Engagements I see tend to fall into three bands. None of these is a quoted rate, and your number can land outside them depending on complexity, scope, and how clean your books already are.

Nothing here is fixed.

One number in this post is, though. KLYVNT's own rate card is public: controller work runs $3,500 a month, fractional CFO $5,500. Not an observation, the actual price list. Most firms in this space make you book a call to hear a number. You just read mine.

Light months stay light. When you are raising or selling, you turn the dial up for that stretch and bring it back down after the dust settles.

Why is fractional cheaper than full-time?

Run the math.

A full-time CFO at the level you actually want is a real salary, often $180,000 to $250,000 plus benefits and bonus (illustrative, not a quoted figure). Your $1-5M business does not have 40 hours a week of CFO-level work waiting for that person. It has maybe a few days a month of it. Buy the full-time seat anyway and you pay a steep premium to keep a senior hire underused most of the week, funding executive-level compensation for stretches of work that a controller or a bookkeeper could carry for a fraction of the cost.

Fractional fixes the mismatch. You pay for the brain, not the chair. And the right time to bring one in is a decision-weight question, not a revenue milestone, so the spend should map to the calls in front of you, not to your top line.

How do you know if you're overpaying?

Price alone tells you almost nothing. What you get for it tells you everything, so judge the deliverable and not the invoice. A few signals the spend is off:

• The work coming back is bookkeeping and cleanup, but the bill says CFO. That is a controller-or-bookkeeper cost wearing a CFO price tag.
• Nothing comes back you can point to. No forecast, no model, no decision you made differently because of the work. Meetings, basically.
• Your books still are not reliable. Pay for forward strategy off numbers you do not trust and you are funding the wrong layer entirely.

Quick test. If you cannot name the last decision this person changed, you are either overpaying or under-using them. Fix one or the other.

The honest bottom line

Cost is the wrong anchor. What you should be asking is whether you are buying the layer you actually need.

Size barely matters.

A clean, predictable business at $4M might want a light $3,500 touch and nothing more. Meanwhile the complex shop at $1.5M that is borrowing, juggling service lines, and eyeing a sale can justify the very top of the range tomorrow, and the spend will pay for itself the first time it catches a bad decision before you make it.

So do not anchor on the price. Anchor on the weight of the decisions in front of you, then pay for the judgment those decisions demand. If you are not sure whether you need a CFO, a controller, or just cleaner books, a short diagnostic usually settles it, and that is the conversation KLYVNT Advisors is built to have before you spend in the wrong place.
